Trivia: In an interview with Leon, he states that he ad-libbed the line "Ain't nobody coming to see you, Otis." Charles Malik Whitfield, who plays Otis, was bothered by this, and his reaction is genuine.
Trivia: There were palm trees near the Popes' home in FL and there were palm trees when they stopped at a motel in SC. Palm trees are expected in tropical and subtropical climates, but certain species can grow anywhere in SC under the right conditions. (This is true to a lesser extent in the warmer zones of North Carolina.) The "Sabal Palm" (A.K.A. "Cabbage Palmetto") is actually South Carolina's State Tree. The palms at the motel looked like "True Date" palms to me but were more than likely "Sabals." (00:02:44 - 00:08:12)
Trivia: The film was made in 1965 and Natalie Wood was born in 1938; she was 27 when she made the film, playing a girl that aged from 13 to 17.
Trivia: When Claudin thinks his concerto has been stolen, he goes into a frenzy and attacks the music publisher. The publisher's assistant, Georgette, stops the attack by splashing a tray full of powerful etching acid into Claudin's face. Oddly, Claudin does not recoil when she throws the acid; rather, he leans forward, as if to ensure that it the liquid strikes him full in the face. Which is precisely what happened. To avoid having to shoot the messy scene more than once, we see actor Claude Rains deliberately leaning into the splash for a thorough dousing.
Trivia: This is the first Pixar movie that does not feature the voice of John Ratzenberger. Instead there is a cameo of an animated version of him.
Trivia: Glenn Close is only twelve years older than John Hawkes, who plays her son.
Trivia: During the show, there is a hair that gets caught in the projector that is removed by Poochini before continuing his performance. The joke was so realistic that many projectionists attempted to remove the hair themselves, not realising that it was part of the cartoon.
Trivia: When Jerry phones the club and informs Mammy Two-Shoes about the party, she runs back home. You can see Mammy Two-Shoes' face for about two frames as she runs back to the house.
Trivia: John "Juke" Logan did the harmonica parts for the soundtrack. He also is the same person who did the harmonica on Home Improvement when the "boys from K&B Construction" did their musical "Ratchet Rhapsody" on Tool Time. If you listen closely, even Rock says "Ol' Juke whipped out his..."
Trivia: Before Leopold (Bugs) begins conducting, he takes the conductor's baton and breaks it. Leopold Stokowski never conducted with a baton, so this is the reason why Bugs breaks it.
Trivia: At the end of the film, Michael Lang mentions he's going to California to put on another free concert with the Rolling Stones. He's referring to the infamous "Altamont concert" where the Hells Angels motorcycle gang provided security, which resulted in a number of people being beaten up, two people dying in a hit-and-run accident, one accidentally drowning, and another being stabbed to death.
Trivia: Meryl Streep's role is the only performance for which Wes Craven directed an actor to an Academy Award nomination.
Trivia: Sissy Spacek was the film's set dresser.
